## What is Trayner AI?

Trayner is your AI coach for training, nutrition, and recovery — a complete fitness companion that plans your workouts, logs your sets, checks your form, tracks your food, and tells you when you're ready to push.

AI FORM CHECK
• Record a short video of your set and get instant, rep-by-rep feedback — squat, bench, deadlift, overhead press and more.
• Trayner scores your form 1–10, calls out the top fixes, and flags the rep that needs the most attention.
• Real measurements — depth angle, bar-path drift, knee valgus, torso angle, elbow flare — not vague advice.
• Every check is saved per exercise, so you can see your trend line, your baseline, and how today compares to last session.

TRAIN SMARTER
• AI-generated routines built around your goal, experience, equipment, and schedule — with a weekly plan that adapts as you log.
• Fast set logging with smart defaults, full history, supersets, rest timers, and one-tap re-runs.
• A 580+ exercise library with demo videos, muscle maps, and how-to cues.
• More than lifting — guided Yoga, Pilates, Stretching, Mobility, Rehab, and Cardio.
• Strength Score, weekly volume, muscle recovery, PRs, and a training roadmap that shows where you're headed.

EAT FOR YOUR GOALS
• Log food by search, barcode, nutrition-label scan, or a photo of your plate — calories and macros in seconds.
• AI meal plans and grocery lists that flex with your training days, plus a daily health score.
• Track water, supplements, and body composition (InBody-style scans) all in one place.

RECOVER + READINESS
• Recovery, Strain, and Sleep insights (HRV, resting heart rate, sleep quality) so you go hard when you're fresh and back off when you're not.
• Stress and Energy monitors, progress photos, and weight & measurement tracking.
• Syncs with Apple Health / Health Connect for steps, sleep, and energy.

ALWAYS WITH YOU
• Home- and lock-screen widgets, an AI coach you can chat with, streaks, and milestone badges to keep you consistent.

BUILT FOR LIFTERS
Whether you're chasing your first bodyweight bench, training for a powerlifting meet, or just trying to stop your knees caving on heavy squats, Trayner gives you the eyes — and the plan — you don't have when you're alone in the gym.

PRIVACY
Your videos stay on your device unless you ask for a form check. Form-check uploads are processed and discarded — nothing is used to train models.

## Version history (last 5 releases)

### 1.4.2 — 2026-09-05

Body Scan (new)
Two photos, front and side, and Trayner measures you: neck, chest, waist, hips, arms, thighs and calves, plus shoulder width and limb lengths. A guided setup walks you through lighting, clothing and posing, and voice guidance talks you into position so you can stand across the room. Results show as honest ranges, with a body-fat estimate from the published Navy method, a skeletal-muscle estimate, waist-to-hip and waist-to-height ratios against WHO and NICE guidelines, and a posture read-out. Explore your figure in a 360° view, compare scans taken under matching conditions, and calibrate against your own InBody or FitQuest readings.

Form Check
Ask Trayner about any rep. Tap a cue on your form report to open a coaching chat seeded with your own results, and pin a fix straight into your plan. A new movement-profile radar shows where each lift is strong or weak across five dimensions. Share a form report, or the raw clip, from the report screen.

Fasting
A new fasting tracker in the Food tab: pick a protocol, start and stop with one tap, and get a reminder when your window opens or closes. Home cards show where you are in the fast.

Also in this release
• Sources & Methodology: every health figure in the app now links to the research behind it.
• More reliable video and photo uploads on slower connections.
• Fixes for translations, Android layout on gesture-navigation phones, and several crashes reported through TestFlight.

### 1.4.1 — 2026-08-19

Updated from SDK 54 to SDK 57

### 1.4.0 — 2026-08-08

Say hello to a faster, cleaner way to get around Trayner:

• New quick-action button — tap + to start a workout, log food, snap a meal, weigh in, ask Trayner and more, all from one place. Press and hold to rearrange it or add your own favourite shortcuts.

• Redesigned navigation bar — a lighter, frosted-glass tab bar with a smooth new highlight as you move between tabs.

• Smoother transitions throughout the app when switching sections.

And more to explore this update:

• Exercise demos now move — looping video clips play across your workout, routines and the exercise library (and pause when off-screen to save battery).

• Refreshed Strength & Form cards on Home — your rank crest and form level now sit in one cleaner card, with each medal coloured to its level.

• Record a form check from anywhere — tap Record a check, then pick a muscle and exercise or just search for a lift, and the camera locks straight to it.

• A clearer workout recap — the Muscle Split now highlights the exact muscles you trained on a full-body map, in each muscle's colour.

• Daily recovery at a glance — each day on the Home calendar strip now shows a ring for that day's recovery score.

• Apple Watch setup made easy — if your watch is detected but not connected, Home shows a quick "Set Up" card that walks you through it. Swipe it away once you're done.

• Plenty of polish and reliability fixes — including tidier coach replies and small design touches — for a smoother, more responsive experience.

Thanks for training with Trayner

### 1.3.1 — 2026-07-20

The exercise experience just got a major upgrade:

• Redesigned exercise details — new About, History, Progress, PRs, Strength and Form tabs put everything about a lift one tap away.
• Full-screen exercise player — tap any demo to zoom in, slow it down, pause, and share, with a quick link to YouTube tutorials.
• Personal Records, reimagined — see your Estimated 1RM, Max Weight, Max Reps and volume records in a cleaner, clearer layout.
• Smarter search & filters — a faster search bar and a single visual filter to browse by equipment or body part.
• Browse the full exercise library right from the Workout tab.
• Bigger, clearer muscle diagrams across the Strength, Form and exercise screens.
• Apple Watch workouts now notify you the moment they're logged.
• Plus lots of polish and reliability fixes for a smoother, faster app.

Thanks for training with Trayner — keep the feedback coming!

### 1.1.0 — 2026-07-17

We've added a "Sources & Methodology" screen (Profile → About → Sources & Methodology, also linked directly from every health, nutrition, and recovery screen and the AI coach) citing the specific formulas and public health guidelines behind our calculations and recommendations — USDA Dietary Guidelines for Americans 2020–2025, Mifflin–St Jeor, the ISSN protein position stand, WHO, the Compendium of Physical Activities, and peer-reviewed research. Each source is a tappable link to a publicly accessible page (no login or paywall). The AI coach now also attributes its recommendations to their sources.

I have also attached a pdf of screenshots of the above implementation.
